Personally I think it is even absurd that someone needs to point this out in a video! As a kid in South America I used to walk 80% of the time barefoot or on sandals. It is clear that in such situation any faster movement needs to be done toe first. So, fighting, dancing, running, would be done toe first in such cultures. On the other hand, heel-first is more energy efficient, so you do that when walking slowly barefoot. It was modern shoes that allowed people to do everything heel-first.
